UW 360 (Atlas 10k) drive with an Adaptec 29160 - Problem: Lo |
|
|
I bougt a fast U 360 drive and could get a cheap Adaptec 29160. Now I wonder
why my data transfer is so extremely low!? I measured with HD Tach 33 MB/s.
My S-ATA disk is about 60 MB/s. As far as I understood the speed should be
at least around 100 MB/s.
My config is:
Mainboard: Abit IC 7G Bios Version 719
P 4 3Mhz Northwood (400 MHz FSB)
512 MB RAM Kingston PC3200 DDR400 RAM
1 WD 160G 7400rpm SATA disk (60 MB/s)
1 WD 80G ATA disk (27 MB/s)
1 WD 30 GB 10000 rpm SCSI 320UW (33 MB/s ????)
Win XP SP2
What is my problem? Have I made a major mistake here? Is there something I
can do? I understand that the PCI bus is a limiting factor (and that
ideally I'd plug it into a PCI-X slot if I had one), but is it really THAT
limiting? THAT slowing?
Help, please! If I made a mistake, maybe I can send this stuff back... |

Update: one problem was my firewall, which slowed down the whole testing
process. I experimented with FileMon from SysInternals and deactivated all
programs with excessive file access which still gives a bad result for the
SCSI drive:
1 WD 160G 7400rpm SATA disk (124 MB/s)
1 WD 80G ATA disk (80 MB/s)
1 WD 30 GB 10000 rpm SCSI 320UW (38 MB/s)

An Atlas 10K is 5 years old. It will be under 40MB/s.

I have a 39160 with Seagate 320 36GB. The speed from 70MB/s to 37MB/s.
Another 60GB ATA100 from 55MB/s to 25MB/s
My board MSI K7T-R
Athlon XP 2400+ (2GHz, FSB 133Mz)
SDRAM 640MB
Win 2k sp4
I think it may be you have win xp sp2.
The sp2 version is slower.
Xp default enable system restore. Try to turn it off.
